The Main Ground Combat System (MGCS) represents a 2017 collaborative effort between France and Germany aimed at succeeding the Leopard 2 and Leclerc main battle tanks. Unlike the French-led Future Combat Air System, MGCS is coordinated by Germany and designed as an integrated system of systems focused on a cutting-edge armored fighting vehicle.
The development and production responsibilities are primarily handled by KNDS, a joint holding company formed in 2015 by the German firm KMW and the French company Nexter Systems. In 2019, Rheinmetall joined the project, introducing complexities regarding leadership and manufacturing shares, which were originally planned to be evenly divided between France and Germany. The finalized arrangement assigns development leadership equally among Nexter, KMW, and Rheinmetall, with Nexter guaranteed half of the production output while the remaining half is split between the two German partners. Production is not expected to commence before 2045.
According to KNDS CEO Frank Haun, several other European nations—including Italy, Norway, Poland, Spain, Sweden, and the United Kingdom]—have expressed interest in participating in MGCS, with discussions ongoing as of 2022.
History
In December 2014, amid the conflict in Donbas during the war in Donbas, the Bundestag authorized initiating development of a new tank generation, recognizing that the existing Leopard 2A6 tanks were insufficient. Analysts highlighted shortcomings of tungsten-based ammunition used by the Bundeswehr compared to depleted uranium rounds, raising doubts about their effectiveness against modern Russian tanks such as the T-80, T-90, and T-14 Armata.
Negotiations began in mid-2014 involving Krauss-Maffei Wegmann, Nexter, and both German and French governments to merge their companies for securing the MGCS contract. In July 2015, the French National Assembly passed legislation enabling privatization steps necessary for KMW and Nexter to consolidate, culminating in a formal agreement signed in Paris on 29 July 2015. The merger was finalized by December 2015 with Stéphane Mayer and Frank Haun appointed as CEOs of the newly formed holding entity.
By 2016, MGCS had entered its conceptual phase with initial completion expected by 2017. At that year’s Eurosatory defense exhibition, Rheinmetall presented an MBT Advanced Technology Demonstrator based on an upgraded Leopard 2A4 Evolution chassis, which later evolved into the Panther KF51. In 2018, KNDS introduced the European Main Battle Tank (E-MBT), which combined a hull derived from the Leopard 2A7 with a lighter turret adapted from a Leclerc, showcasing Franco-German collaboration on next-generation armored vehicles.
In May 2020, Germany’s armed forces procurement agency awarded a contract for a System Architecture Definition Study to a consortium comprising Rheinmetall, Nexter, and KMW (KNDS). This 18-month study aims to align requirements and establish a multi-platform architecture framework for MGCS. This effort forms part of the Technology Demonstration Phase (TDP), targeted for completion by 2024, followed by a system demonstrator phase extending through 2028 prior to full production and testing.
Initially planned in June 2018 for deployment around 2035 with full operational capability by 2040—dependent on export customer acquisition—MGCS attracted interest from Italy and Poland by August 2019 as potential participants seeking inclusion in EU defense initiatives like PESCO. Spain also expressed intentions in September 2019 to replace its fleet of Leopard 2E MBTs with MGCS once available.
During a February 2020 visit to Warsaw, French President Emmanuel Macron signaled openness toward Polish involvement despite earlier French reluctance to expand partnership before concluding initial studies. Concurrently, South Korean manufacturer Hyundai Rotem negotiated licensed production of the K2 Black Panther tank in Poland under the "Wilk" (Wolf) Program aimed at modernizing Poland’s armored forces.
In June 2020, Italy’s Defence Undersecretary Giulio Calvisi indicated Italy’s potential entry into MGCS. Frustrated by program delays, Italy also proposed developing its own tank project while seeking collaboration with countries like Poland and Spain.
By November 2021, the Netherlands requested observer status within MGCS; France and Germany engaged in negotiations regarding conditions for new participants but recognized Dutch strategic significance. In January 2022, Belgium increased defense expenditure plans including intentions to join MGCS.
Following the onset of the 2022 Russian invasion of Ukraine, Poland signed an agreement in July 2022 to procure 1000 K2PL Black Panther tanks and collaborate with South Korea on next-generation armored vehicles. Due to MGCS’s extended timeline, Poland chose not to join MGCS.
In 2025, Germany approved forming the MGCS-Project Company as a joint venture dedicated to vehicle development. Subsequently in April 2025, representatives from KNDS Deutschland, KNDS France, Rheinmetall, and Thales established MGCS Project Company (MPC) based in Cologne to act as the industrial prime contractor responsible for coordination and integration efforts.
Design
The French-German joint research institute, Institute of Saint-Louis (ISL), describes MGCS as an advanced land combat system integrating both uncrewed (including autonomous) ground and aerial platforms with manned vehicles spanning light, medium, and heavy categories, all equipped with coordinated weapon systems. Rather than relying on a single vehicle, the initiative focuses on delivering capabilities equivalent to those of main battle tanks through innovative tactics and enhanced collaborative combat functionalities, necessitating novel vehicle concepts.
At Eurosatory 2018, KNDS presented a prototype merging the hull, powertrain, and chassis of a 68-ton Leopard 2A7 with the more compact, autoloader-equipped turret from the Leclerc tank. Francois Groshany, Nexter’s director of tracked and armour programs, highlighted that this combination leverages the "exceptional performance" of the Leopard 2 chassis together with the lighter Leclerc turret, which weighs approximately 6 tons less than its Leopard 2 counterpart. This weight reduction enhances maneuverability and enables passage over bridges that cannot support heavier tanks.
On 26 April 2024, the defence ministers of France and Germany established MGCS’s core technology areas along with their respective national leads:
- Pillar 1 – MGCS platform encompassing chassis and automated navigation (led by Germany)
- Pillar 2 – Development of gun systems, turret, and ammunition including joint testing for system selection (jointly led by France and Germany)
- Pillar 3 – Secondary weapon systems such as guided missiles (led by France)
- Pillar 4 – Communication, command, and deployment infrastructure (jointly led by France and Germany)
- Pillar 5 – Simulation environments (joint leadership between France and Germany)
- Pillar 6 – Sensor technologies (led by France)
- Pillar 7 – Defensive measures including protection and counter-drone capabilities (led by Germany)
- Pillar 8 – Support services, logistics, and infrastructure (jointly led by France and Germany)
